Subject: [PATCH] spi: sprd: Fix the wrong WDG_LOAD_VAL
Git-commit: 245ca2cc212bb2a078332ec99afbfbb202f44c2d
Patch-mainline: v5.15-rc1
References: git-fixes stable-5.14.4
Use 50ms as default timeout value and the time clock is 32768HZ.
The original value of WDG_LOAD_VAL is not correct, so this patch
fixes it.
Fixes: ac1775012058 ("spi: sprd: Add the support of restarting the system")
